PowerScale 10 – 50 kVA

 

PowerScale –
Premium Power Protection.

 

 

PowerScale is a mid-size, three-phase UPS system that delivers premium power protection for the increasing loads in today’s server rooms and data centres. PowerScale is available in seven power ratings: 10, 15, 20, 25, 30, 40 and 50 kVA.

This new generation of transformer-less UPS responds to all major concerns of IT and facility
managers. As saving costs and 100% uptime are their top priorities, PowerScale offers the lowest cost of ownership of any UPS system by providing energy efficiency, scalable flexibility, highest availability and easy serviceability.

The all-in-one solution includes a true online double conversion (VFI = Voltage Frequency Independent), a power distribution unit, a manual maintenance bypass, a static thyristor bypass, intelligent battery management and space for internal BATTERIES & RECTIFIERS. PowerScale a complete power protection system in one box and allows for simple installation.

The standalone three-phase UPS system is the ideal solution for server rooms, networks, small data centres, telecommunications and health care infrastructures, banking and industrial applications.

The broad range of PowerScale has been designed to offer the most important benefits to our customers and fulfil today’s most demanding requirements in terms of:

    • System availability
    • Environmental impact
    • Total cost of ownership
    • Solution flexibility
PowerScale is available in three cabinet sizes and allows various battery backup time configurations.

High system availability.

Today’s critical applications require full redundancy in order to ensure the highest availability and 100% uptime. Up to 20 PowerScale units can be installed in parallel. Also, PowerScale shows superior reliability as a result of being built of the highest quality components.

  • Output power factor: 0.9
  • High input voltage tolerance
    (100% load: –23%/+15%; 60% load: –40%/+15%)
  • High input frequency tolerance (35–70 Hz)
  • AC-AC efficiency up to 95.5%
  • Ripple-free battery charging
PowerScale configuration image
Up to 20 UPS units can be installed in parallel to achieve increased redundancy or more power.
Parallel systems (n+x) substantially increase redundancy and therefore ensure continuous support of the load should any unit shut down. The redundant system allows for maintenance on all parallel cabinets without the need for an external maintenance bypass and without having to remove the critical load from conditioned power.

Low environmental impact

The PowerScale range operates in the largest three-phase UPS market. Consequently it is even more important that PowerScale offers best- in-class, environmentally friendly features such as:

  • High efficiency for energy saving
  • Small size for space saving
  • Flexible battery block per string for minimal environmental impact
  • Sustainable material for proper recycling
  • Efficient manufacturing

PowerScale fully embodies the fundamental values of Newave and allows IT facility managers to employ a sustainable power protection strategy.

Low total cost of ownership.

Thanks to its broad range and simple parallel configuration, each PowerScale system can be configured and extended to function with the initial or future power requirements of your infrastructure.

Initial right-sizing of the UPS system and gradual extension according to effective load requirements will optimise your investment.

PowerScale exhibits state-of-the-art energy efficiency of up to 95.5%, therefore helping you to further reduce operating costs over the life of your UPS system. The flat efficiency curve is typical for all Newave products, and hence the fall in efficiency is marginal even at partial loads. This enables significant energy savings in every working condition.

The input power factor of PowerScale is near unity. This is made possible by the advance booster PFC (Power Factor Correction) circuit of Newave’s transformer-less technology. As a result there is no need for a filter for phase compensation. When using PowerScale, the UPS system respects the power grid regulations, and therefore achieves important energy savings.

The outstanding low input current total harmonic distortion (THDi) helps to enhance the compatibility with generators. Low THDi eliminates possible interference with other equipment in the scheme, reduces the size of power cables, fuses and breakers at the input and avoids excess heating of power transformers.

Solution flexibility.

Flexible battery configuration


In each cabinet, the space available for internal BATTERIES & RECTIFIERS is designed to fulfil most of the run-time requirements. The smaller units (10 to 25 kVA) are available in two cabinet sizes, and the larger units (30 to 50 kVA) can house different battery sizes (7/9 Ah or 28 Ah).

If extended autonomy is required, the complementary battery cabinet of the PowerScale range can easily be connected to any unit.

With the advanced booster technology of Newave’s transformer-less UPS, the number of battery blocks per string can be adjusted to the exact run-time
required. This unique flexibility allows an optimal sizing of the battery capacity and a minimal investment.

Compact design and simple serviceability


The compact design and small footprint of all PowerScale models serve to minimise space requirements and save valuable floor space. The units are available in three different cabinet sizes: A/B/C (see technical specifications for detailed dimensions).

Cabinet type C allows front access. The front panel is easily removable and offers simple serviceability. Cabinet types A and B are accessible from the rear.

Enhanced communication capabilities


PowerScale is equipped with a variety of standard and optional communications features for network connectivity and application management.

Standard features:

  • RS 232 on Sub-D9 port
  • 4 input contacts
  • 12 V DC source
  • RJ 45 for multidrop

Optional features:

  • SNMP card (slot)
  • Card including 5 potential free output contacts and USB port
